Ribosomal protein S1



Ribosomal protein S1 (RPS1) is one of the 22 proteins which belong to the small subunit of the bacterial ribosome. It participates in translation initiation of many mRNAs and plays a role in translation elongation. It consists of 6 repeats of 70-residue domains able to bind single-stranded nucleic acids named OB folds. The images at the left and at the right correspond to one representative RPS1, i.e. the NMR structure of the domain 4 of the Escherichia coli ribosomal protein S1 (2khi).
